New for 2017, the second-generation Q7 is up to 325 kilograms lighter than the previous version, while boasting more than a few new technologies. The full-sized crossover is available with a choice of two engines: a turbo-four with 252 hp and 272 lb.-ft. or a V6 producing 333 hp and 325 lb.-ft. With both models, power is transmitted through a new eight-speed manumatic transmission to the Quattro AWD system.
